Every few minutes, the touch screen function disappears - I can continue to use the laptop conventionally with keyboard and mouse, but the touch screen is dead. I go into Device Manager: Human Interface Devices - HID-compliant touch screen - Driver, then hit Disable, Yes, and then Enable. With the driver re-enabled, the touch screen works perfectly for a while, until it stops again and has to be re-disabled and enabled.
It seems as if this is a driver issue. Has anyone else experienced this? Is there a workaround?
